Role overview
Summary
As a Senior Embedded Software Engineer in SumUp’s Hardware Tribe, you will play a central role in bringing up next-generation Android-based payment devices. This involves working on bootloader, kernel, framework integration, and validation for highly customized, security-focused hardware products.
About the role
As a Senior Embedded Engineer in SumUp’s Hardware Tribe, you will be part of a small and highly skilled cross-functional team working alongside Hardware Engineers, Product Managers, QA Engineers, and more. You will play a central role in bringing up SumUp’s next-generation Android-based payment devices — from bootloader and kernel all the way through to framework integration and validation.
This is a relatively new role as SumUp transitions to the Android platform for its in-house hardware products. Unlike most Android devices, our hardware is a highly customised, security-focused payment device built from scratch — requiring a deep understanding of both embedded hardware and software.
The role is based on-site in our office in Berlin. We believe in the power of face-to-face conversations that happen organically when working next to one another.
What you’ll do
Perform system bring-up for the Android Embedded platform, including bootloader, kernel, and driver integration
Develop and integrate SumUp custom modules — including kernel drivers, power management, and connectivity components
Maintain and improve the build system, ensuring stability and scalability across the platform
Debug hardware and software issues at the protocol level (I2C, SPI, UART, SDIO, etc.)
Carry out testing and validation to ensure new releases are delivered with the right quality and on time
Collaborate closely with Hardware Engineers, QA, Product Managers, and Manufacturing/Supply Chain teams
Independently deliver features on Android OS and contribute to a culture of engineering excellence within the Hardware Tribe
You’ll be great for this role if:
You have 5+ years of professional experience in embedded systems development with a strong focus on Android & AOSP
You have hands-on experience debugging hardware interfaces at the protocol level (I2C, SPI, UART, SDIO, etc.)
You have deep knowledge of the Android OS architecture — from bootloader (U-Boot, Little Kernel) and kernel to the framework and services
You have expert-level proficiency in C programming for embedded Linux environments
You have hands-on experience with at least one of the following platforms: Qualcomm Snapdragon or MediaTek
You have solid understanding of embedded security concepts: Secure Boot, TrustZone (TEE), dm-verity, file-based encryption, and hardware-backed key storage
You have proficiency with embedded debugging tools (e.g., JTAG, logic analyzers, kernel debuggers)
Why you should join SumUp
The opportunity to work on large scale fintech products used by millions of small businesses around the world
A dedicated annual Learning & Development budget for attending conferences and/or advancing your career through further education
Enrollment onto our virtual stock ownership program - you will own a stake in SumUp’s future success
A corporate pension scheme
28 days paid leave + 1 for birthday
You’ll attend global offsites and/or hackathons.
You'd enjoy other great benefits such as Urban Sports Club subsidy, Kita placement assistance, subsidized office lunches and other location-tailored benefits, Babbel language platform subscription and more!
